IMPROVEMENT IN SASH-FASTENERS.

Specification forming part of Letters Patent No. 148,604, dated March17, 1:574; application filed February CASE B.

'lo all whom it may concern:

Beit known that I, WVILLIAM T. FRY, of the city of Brooklyn, county ofKings, State of New York, have invented certain Improvements inSash-Fasteners, of which the following is a specification:

The object of my invention is to provide for a sashfastener having aguard, which will prevent access to the room from the outside, and whichalso forms a frame for the spring-catch of the sash-fastener, incombination with said spring-catch provided with a projection in orderto move the same by the hand. Said spring-catch fits into a ratchet-barplaced on the side of a window-sash, where'the same slides into theframe.

In order to prevent persons from the outside from inserting aninstrument between the sashand the frame, and thus be enabled to forcethe spring-catch from the ratchet-bar, the guard, also forming the framefor the spring-catch, is placed outside the spring, slidin g in a groovecut into the sash.

In order to more fully describe my invention, I refer to theaccompanying drawing forming a part of this specification.

Figure I is an inside view of awindow frame and sash with a part removedembodying my invention. Fig. II is a detached front view of thespring-catch. Fig. III is a detached front view of the ratchet-bar.

A represents a window-frame; B, the sash; O, the spring-catch; E, theratchet-bar; F, the guard; G, the groove in thesash B.

I am aware that a spring-catch and ratchetbar is used as asash-fastener, and I do not claim this to be my invention.

What I desire to claim is The guard F, bent up from the face-plate,where it forms a frame for the spring-catch (J, and the groove G, incombination with the ratchet-bar E, substantially as and for the purposeset forth.

WM. T; FRY.
